Maybe this would be a good feature to have, but going back to the
original problem of bookmark file, I think that the easiest fix is to
go back to using write-file.  Karl changed that 15 years ago because
he followed suit of saveplace.el, but I think there's a significant
difference between the files these two packages maintain: the file
with bookmarks is much more close to being "user data" than the file
written by saveplace.el.  So I don't think they need both to treat
their files the same, wrt backing them up.
